1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Cold-chain requirements affect worldwide distribution of many vaccines. In addition, vaccines requiring multiple doses impose logistical and financial burdens, as well as patient compliance barriers. To address such limitations, we have developed new technologies to prepare thermostable, single-shot, prime-boost microparticle vaccines. Antigen/adjuvant formulations containing glass-forming polymers and trehalose first are spray-dried to form glassy microparticles that confer thermostability. Atomic layer deposition (ALD) reactions conducted in fluidized beds are then used to coat the microparticles with defined numbers of molecular layers of alumina that modulate the timed release of the internalized antigen and act as adjuvants. We have used a model HPV16 L1 capsomere antigen to evaluate the properties of these technologies. Thermostabilized powders containing HPV16 L1 capsomeres were prepared by spray-drying, coated by ALD with up to 500 molecular layers of alumina, and injected into mice. Antigen distribution was assessed by live-animal IR dye tracking of injected labeled antigen. Antibody responses were measured weekly by ELISA, and neutralizing antibodies were measured by pseudovirus neutralization assays at selected time points. Thermostability was evaluated by measuring antibody responses after incubating ALD-coated antigen powders for one month at 50 °C. Single doses of the ALD-coated vaccine formulations elicited a prime-boost immune response, and produced neutralizing responses and antibody titers that were equivalent or superior to conventional prime-boost doses of liquid formulations. Antibody titers were unaffected by month-long incubation of the formulations at 50 °C. Single-dose, thermostable antigen preparations may overcome current limitations in HPV vaccine delivery as well as being widely applicable to other antigens.
